The crystallizer is the key component controlling the solidification process and is mainly made of pure Cu. The poor wear resistance and oxidation resistance of pure Cu limit the working life of the Cu crystallizer. Herein, Fe/FeCr coatings are designed and successfully fabricated on the Cu substrate by laser cladding technique. The composition, microstructure, mechanical, and thermal properties of the Cu–Fe/FeCr composite are investigated. The coating is composed of a body‐centered cubic Fe–Cr alloy phase. The grains on the surface are equiaxed grains with an average diameter of 2 μm. The coating exhibits a tensile strength 3 times of Cu substrate and well elongation thanks to the fine‐grain structure. The interface between coating and substrate is metallic bonding and possesses a shear strength of as high as 200 MPa. The coating shows obvious advantages in wear resistance and antioxidation at high temperatures in comparison to Cu substrate. The laser cladding Cu–Fe/FeCr composite is promising to prolong crystallizer life for continuous casting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
